7.6 Anti-cold air function in heating mode
After entering heating mode, or last defrosting is over, the compressor will start up, if Tg
＜
28
℃
,
indoor motor will stop; if 38
℃>
Tg
≥
28
℃
, indoor motor will run at low speed; if Tg
≥
38
℃
or the
compressor has run for over 4 minutes, indoor motor will run at the set speed; once the motor has
started up, it will not stop because of Tg reduction.
7.7 Blowing remaining heat function
In heating mode, the thermostat is OFF, the compressor stops, indoor motor will run at low speed
until Tg
＜
28
℃
and has run for 50 seconds at least.
Note: in heating mode, “the compressor stops----indoor motor delays to stop” adjust if the pipe
blows remaining heat; “the compressor startup----indoor motor delays to start up” adjust if the pipe is
anti-cold air; in other conditions, the compressor and the indoor motor are allowable not to be in
company. In cooling mode, the motor will run according to the control, not together with the
compressor.
7.8 Defrosting function in heating mode
In defrosting and when the compressor resumes to run for 3 minutes after defrosting is over, the unit
will not adjust the sensor failure.

minutes in all and has run for over 10 minutes continuously. b) the compressor and outdoor fan
running normally. c) the temp. of indoor coil sensor lower than 45
℃
, d) the defrosting temp. lower
than –8
℃
(use the defrosting start signal from outdoor in the condition of with outdoor
communication ).
7.8.3 Auto defrost quit condition: The defrosting temp. over 14
℃
or the defrosting time is over 12
minutes (use the defrosting end signal from outdoor in the condition of with outdoor communication )

valve runs and compressor starts up. The indoor fan motor will run at anti-cold air condition.
7.8.5 For the unit with auxiliary electric heating function:
a. If the auxiliary electric heating function is working when the defrosting condition is met, please
stop electric heater firstly, 20 seconds later, defrosting can begin;
b. After defrosting, the unit will adjust the working state of electric heater according to the setting
before defrosting.
7.9 Auxiliary electric heating function (valid in heating mode or heating state in AUTO mode)
Enter condition: 1)
Δ
T>1; 2) Thermostat ON and running for 1 minute; 3) Tr<26
℃
; 4) Indoor motor
running; 5) Electric heating function start signal available (cancelled); 6) The system working in
heating mode or in heating state of AUTO mode; 7) Tg<48
℃
If the above conditions can all be met, the electric heating function will work.
Quit condition: 1)
Δ
T
≤
1; 2) Thermostat OFF; 3) Tr>26
℃
; 4) Indoor motor stops; 5) Electric heating
function start signal not available (cancelled); 6) The system in non-heating operation; 7) Tg>52
℃
If one of the above conditions can be met, the electric heater will stop.
8. FAN mode control
The compressor and the outdoor motor will stop running, indoor motor can be set at
high/med/low speed, the fan blade can swing or stay at one position. In this mode, you can set the
TIMER and SLEEP function.
9. CLOCK setting and TIMER function
The unit can set 24-hour TIMER ON/OFF, and the min. unit is 1 minute, after being set, the timer
lamp of indoor will be on, and after the timer is over, the timer lamp will be off.
TIMER ON: RUN LED is off, compressor LED is off, and TIMER LED is on, the unit is in stop state.
When timer is over, the unit begins to run, and the timer LED is off. The unit operation begins from
